Measured average deviation for Poly Lactic Acid (PLA) parts made by Fused Deposition Modeling

Nine dimensional features (length, width, height, location, three concentric cylinders, minor and major axes of ellipse) have been measured thrice from the sixteen PLA parts printed and the calculated average deviations are listed here. Each of the sixteen parts are produced with different machine parameter settings as per the designed Design of Experiment (DOE). The dimensional deviation of PLA parts made by Fused deposition modelling is obtained from the difference between actual dimensions and the designed dimensions. Designed dimensions can be obtained from the drawing of the part produced and actual dimensions are measured from the part itself.
